Definitions
- THE HEART OF THE INVENTION IS THE FINDING THAT A WASTE MATERIAL CONTAINING BIOLOGICALLY DIFFICULT TO DEGRADE HALOGEN-, NITROGEN- AND/OR SULFUR AND CONTAINING BETWEEN 0.1 AND 60 WT.% HALOGEN AND UP TO 10 WT.% SULFUR AND/OR SMALL AMOUNTS OF NITROGEN COMPOUNDS CAN BE CLEANED BY REFINING AND/OR ELIMINATION BY CATALYTIC HYDROGENOLYSIS OF HALOGEN-, NITROGEN- AND/OR SULFUR COMPOUNDS WHICH ARE DECOMPOSED WITH FORMATION OF HYDROGEN HALOGENIDE, AMMONIA,HYDROGEN SULFIDE RESP.
- THE INVENTION IS ELUCIDATED IN BUT NOT RESTRICTED TO THE FOLLOWING EXAMPLES AND BY THE FOLLOWING FIGURES.
- FIGURE 1 IS VERY SUITABLE FOR THE CLEAN-UP OF LIGHTLY CONTAMINATED HYDROCARBON MIXTURES.
- THE CONTAMINATED HYDROCARBON MIXTURES E.G. GASOIL CONTAMINATED BY HALOGEN-, NITROGEN- AND/OR SULFUR COMPOUNDS SUPPLIED BY LINE 1, IS FILTERED IN FILTER 2 AND SUBSEQUENTLY MIXED WITH HYDROGEN FROM LINE 14 (AS DESCRIBED LATER ON), IS PASSED TO HEAT EXCHANGER 4 VIA LINE 3. HEREIN THE MIXTURE IS HEATED TO A TEMPERATURE OF 250-400°C, WHICH TEMPERATURE GIVES THE BEST RESULT IN THE SUBSEQUENT ADSORPTION AND HYDROGENOLYSIS STEPS.
- THE EFFLUENT FROM THE HYDROGENOLYSIS REACTOR 7 IS COOLED TO A TEMPERATURE OF ABOUT 50°C IN COOLER 9 BY MIXING THE EFFLUENT WITH A COOLANT (E.G. WATER).
- THE TOP PRODUCT STREAM FROM THE FIRST FILM EVAPORATOR 26 IS PASSED VIA LINE 35 AND CONDENSOR 36 TO SEPARATOR 37, IN WHICH A HYDROCARBON AND HALOGEN-, NITROGEN-, AND/OR SULFUR COMPOUNDS CONTAINING PHASE IS SEPARATED WHICH IS PARTLY RECYCLED BY LINE 39 AND PARTLY GOES TO THE HYDROGENOLYSIS REACTOR BY LINE 40 AND LINE 34.
- THE TOP PRODUCT FROM FILM EVAPORATOR 28 IS SUPPLIED VIA LINE 29 AND CONDENSOR 31 ALSO TO A SEPARATOR 32 IN WHICH A >PHASE COMPRISING HYDROCARBON AND HALOGEN-, NITROGEN-AND/OR SULFUR COMPOUNDS IS SEPARATED AND DISCHARGED BY LINE 33.
- PART OF THIS PHASE IS RECYCLED TO THE FILM EVAPORATOR;THE REMAINDER IS SUPPLIED TO THE HYDROGENOLYSIS REACTOR BY LINE 34.
- THE VOLATILE PHASE FROM SEPARATOR 32 IS DISCHARGED AND SUPPLIED TO SCRUBBER 42, IN WHICH VALUABLE COMPONENTS SUITABLE FOR THE HYDROGENOLYSIS ARE OBTAINED AND FED VIA LINE 34. GASEOUS COMPONENTS ARE SEPARATED AND DISCHARGED.
- HYDROCARBONS AND REMAINING HALOGEN-, NITROGEN- AND/OR SULFUR COMPOUNDS IS DISCHARGED FROM SEPARATOR 36, HEATED TO 250-400°C IN HEAT EXCHANGER 38 AND SUPPLIED TO A SECOND HYDROGENOLYSIS REACTOR 39, WHERE THE MIXTURE IS CONTACTED WITH A HYDROGENATING CATALYST AND THE HYDROGENOLYSIS OF THE HALOGEN-, NITROGEN- AND/OR SULFUR COMPOUNDS IS COMPLETED.
